Stop Guessing Your Supply Chain. Verify with Real Trade Data. If you are tired of dealing with hidden trading company markups, unreliable manufacturers, or unexpected customs delays, I am here to secure and optimize your international operations. As a Fractional Import-Export & Sourcing Consultant with over 25 years of hands-on seniority, I help companies bypass middlemen and audit their entire supply chain architecture using hard customs data. What I Bring to Your Project: • Verified Supplier & Product Sourcing: I trace global shipments to identify original, primary manufacturers—saving you from agent overheads. • Trade Intelligence & Supply Chain Mapping: Using tools like Volza, Big Trade Data, and Trade Map, I legally audit your competitors' suppliers and verify actual import-export records. • OEM & Technical Sourcing: Extensive experience in handling custom factory productions, technical product specifications, and industrial quality compliance. • Customs, Tariff & HS Code Optimization: Correctly classifying goods to reduce tariff risks and ensure seamless cross-border compliance. Industry Specialization: Chemicals & Industrial Goods While I have successfully managed international procurement for a wide range of industrial equipment, raw materials, and textiles, I possess a deep, specialized niche in Chemical Raw Materials, working directly with global production and distribution networks. My Working Model: I operate on a fractional basis (15–30 hours per week), offering ongoing, retainer-based strategic support. You get the oversight of an enterprise-level Trade Director without the full-time executive overhead. 🛑 Please Note: My services are strictly data-driven procurement and actionable sourcing. I do not provide generic web research, SEO leads, or simple scraping. Let's discuss how we can de-risk your next shipment. Click "Invite" to start the conversation.

Create leverage. That is what I do. I build high-performance, secure, reliable software that helps founders and businesses launch and scale with confidence. Since 2010, I have helped founders and established companies turn ambitious ideas, messy workflows, and broken systems into serious software products. Obsession with quality, complete transparency, and no hand-holding - that is how I turn software from a development expense into a business asset. I am an excellent fit if: - You are a founder with a product idea and need more than “someone to code it.” I can help you refine the concept, define the right MVP, validate technical assumptions, choose the right architecture, build the first production-ready version, and support you after launch as the product grows. - You are an established business looking to build a new platform, automate operations, replace spreadsheets, improve workflows, modernize legacy software, scale an existing product, or rescue a bad build. I am especially valuable when the project is too important to gamble on cheap execution, unclear ownership, fragile architecture, or developers who only wait for task lists. I have spent 15+ years building software where failure is expensive, across product types, workflows, and industries including SaaS platforms, AI/RAG systems, internal tools, dashboards, CRM/ERP/POS systems, logistics platforms, marketplaces, real estate software, e-commerce, FinTech, EdTech, HealthTech, data analytics, travel, hospitality, and regulated sports betting The value of that experience is not just knowing different industries. It is knowing the patterns behind them: workflows, permissions, payments, reporting, integrations, data integrity, performance, edge cases, and the business logic that quietly decides whether a product becomes scalable or painful. I personally lead architecture, planning, communication, and delivery. When a project needs more capacity, I bring in my senior team to provide high-level technical ownership and reliable execution. Whether you are a non-technical founder, an operations-heavy business, or a technical team that needs senior delivery support, I will communicate at the right level: clear when needed, technical when useful, and always focused on decisions that move the project forward. I am based in Turkey and regularly work with US, UK, Canadian, European, and Australian clients. I work EST hours with reasonable PST overlap, so communication across time zones is smooth. Don’t settle for mediocre. In a world of ruthless competition, make me your unfair advantage. Send me a message today, and I will map our next steps.

I engineer end-to-end spatial data pipelines and custom WebGIS platforms. My focus is on high-level geospatial architecture—solving structural bottlenecks to build repeatable workflows, clean spatial databases, and practical mapping systems that operational teams can actually use. Recent US project work includes address matching and territory planning for operational teams, public facing GIS maps for policy and exhibition use in Omaha, property and building height analysis in Los Angeles, and a browser based weather graphics platform built with MapLibre, radar layers, timeline controls, and export ready map views. International work includes site selection analysis in Germany, parcel and location intelligence workflows, PostGIS and QGIS topology cleanup, UK air quality grid matching, raster processing, and WebGIS tools built with MapLibre, Google Maps API, AWS, and spatial databases. I can support projects involving GIS analysis, WebGIS dashboards, PostGIS workflows, raster and remote sensing analysis, automated geospatial pipelines, and custom mapping tools. If you need a one time analysis, a repeatable GIS workflow, or a full WebGIS prototype, I can take the project from raw data to final deliverable with a clear technical process.

I help traders take strategies that already make sense and turn them into systems they can run live with confidence. I am an active trader and a systems developer, so I focus on execution quality as much as strategy logic. I build fast execution systems in Python and C++, and I spend most of my time solving the problems that show up in live trading: latency, order routing, broker quirks, webhook failures, exchange edge cases, and the gap between a clean backtest and real execution. My work sits at the intersection of trading automation and applied AI. I build Pine Script strategies and indicators, Python and C++ execution systems, TradingView webhook automation, broker and exchange API integrations, Polymarket automation, and AI-powered research and analysis workflows that help traders make better decisions and operate more efficiently. 🔌 Brokers, exchanges, prediction markets, and market/data systems I have worked with include: Interactive Brokers (IBKR), Tradovate, Bybit, BingX, Binance, KuCoin, Polymarket, Databento, Polygon, Bookmap, Solana RPC, DexScreener, and Jupiter. 🤖 On the AI side, I build workflows using LangGraph, LangChain, RAG pipelines, Neo4j, and LLM APIs. That includes multi-agent research systems, market structure analysis, liquidity analysis, and decision-support tools that help process market information faster and more consistently.
